How to install your eSIM — iPhone

Last updated: May 14, 2026

Before you begin: device is carrier-unlocked (Settings → General → About → Carrier Lock must say No SIM restrictions), QR code or activation code is ready, connected to Wi-Fi, and if two SIMs are already active temporarily disable one.

Important: this eSIM profile installs on one device only. Once you complete installation here, the profile cannot be reinstalled on another device. If you change phones later, request a new profile through the app. See How do I transfer my eSIM to a new device?

Option 1 — QR code (recommended when you have a second device)

  • Settings → Mobile Service → Add eSIM → Use QR Code
  • Point your iPhone camera at the QR code displayed on the other device
  • Tap Continue and follow the on-screen steps

Option 2 — QR code on the same device

  • Settings → Mobile Service → Add eSIM → Use QR Code → Enter Details Manually
  • iOS will offer to use the code it detected in your email or clipboard
  • Follow the on-screen steps

Option 3 — Manual activation code

  • Settings → Mobile Service → Add eSIM → Use QR Code → Enter Details Manually
  • Paste your full activation code including LPA:1$
  • Tap Next and follow the on-screen steps

After installation

Set the new line as your primary data line under Settings → Mobile Service. Signal should appear within a few minutes.
